We went to the hospital today because of my fiance feeling lightheaded like he was about to pass out and he can hardly hold his own weight. He gets so weak he cant even open his eyes or talk. The dr took blood work sugar tests ekg tests and listened to his heart. Everything came back normal. When he gets these spells he feels something around where his diaphragm is at. This has been going on for about 3 months now. When it happened before we was at the hospital and they said vertigo so they have him a shot of valium. Once they did this his heart rate went down to 17 and stopped twice. He was then sent to icu but later felt fine. The drs were thinking it was his heart just because of the shot. But it turned out it wasn't his heart as he was on a heart monitor for a week and everything came back perfect. Does anyone know what could possibly be causing these spells? I'm very worried that I'm losing him. We thought it was blood pressure but that came back perfect We also thought that it was diabetes or cancer but its neither of those. Any help would be appreciated. Thank you.
